1. Avoid eating the in-flight mealLoaded with salt, sugar and preservatives, the inflight meal will not only give you love handles quicker than you can say ‘Cadbury’s’, but it’ll also keep you awake, by virtue of the fact that in-flight meals – on the whole – are near impossible for your body to digest. Eat a meal on the ground before the flight instead (and no, a pint does not count as a meal).

2. Drink plenty of waterAlcohol will dry out your skin (in addition to the dehydrating effects of all that
nasty air conditioning) and though it might knock you out pretty fast, it'll
ensure you have an interrupted night’s sleep. Instead, stock up on water an
hour or so before you go to sleep and drink plenty upon waking.

4. Wear an eyemaskApply
some eye cream
and wear an eye mask, this will help keep the delicate area
under your eye hydrated but also prevent any unwanted rays of sunlight waking
you up an hour into your kip. Earplugs will probably help too.

3. Use a serumThe key to looking fresh at the end of a long flight is to keep your skin super-hydrated.

Short of waking up every hour to apply some heavy duty night moisturiser,
the best thing to do is give yourself a super concentrated hit of hydration – a few drops of this serum from Biotherm, which comes imbued with Blue Algae Extract + Pro-XylaneTM, should do the trick.

5. Brush your teethSounds simple but the key to feeling fresh, and fooling your body into thinking that you’re actually ready for bed, is to follow the same routine as you would at home. Therefore, give your teeth a proper brush before you bed down and the moment you wake up. It’ll also help people believe that you’re half human by the time you make it to your breakfast meeting.
